ELECTRIC SYSTEM
6.7.4 CHECKING THE DIODE OPERATION
N
Remove the fuel tank, see 7.1.1 (REMOVAL OF THE
FUEL TANK).
N
Disconnect the two-way connector (1).
a
CAUTION
Upon reassembly, make sure that the electric con-
nector (1) is correctly coupled.
Using a tester (in diode test mode), check the values be-
tween the two male terminals in the diode, as illustrated in
the figure.
Correct value (measurement A): 0 – 1 Ω
Correct value (measurement B):
In the event the tester does not feature the diode test
mode, power with a voltage of 12 V, placing a 12 V – 2 W
bulb on the positive cable and connecting the diode as il-
lustrated in the figure.
a
CAUTION
Do not use bulbs over 2 W, since the diode may be
damaged.
Test (C): the bulb does not light up.
Test (D): the bulb lights.
If the resulting values do not correspond to the those indi-
cated, change the diode.
N
Repeat the procedure for the other diode.
